Studies of continuum states using angular correlation techniques (II). ^2^4Mg
A study of the region of excitation energy between 17.5 and 22 MeV has been carried out using angular correlation techniques. Alpha decays of continuum levels populated using the ^1^2C(^1^6O, α) ^2^4Mg reaction were observed to the ground state and first two excited states of ^2^0Ne. Double (α-α) an...

| 520 | |a A study of the region of excitation energy between 17.5 and 22 MeV has been carried out using angular correlation techniques. Alpha decays of continuum levels populated using the ^1^2C(^1^6O, α) ^2^4Mg reaction were observed to the ground state and first two excited states of ^2^0Ne. Double (α-α) and, in some cases, triple (α-α-γ) angular correlation measurements were carried out for levels at E"x = 17.60, 17.86, 18.19, 18.56, 19.14, and 21.3 MeV. Branching ratios were determined for all of the above levels plus additional states at E"x = 19.37, 20.57 and 20.90 MeV. In most cases spin assignments could not be made from the angular correlations, either because of a strong continuum background or because the groups turned out to consist of more than one level. A search for a direct γ-decay branch of the E"x = 21.3 MeV level was carried out; a limit Γ"γ/Γ < 0.013 was obtained, in disagreement with a previously reported experiment. While the present work shows that the observed 21.3 MeV peak does not consist of a single state, the measured triple correlations provide some evidence for a J"π = 10^+ level at this energy. | ||

| abstract |
A study of the region of excitation energy between 17.5 and 22 MeV has been carried out using angular correlation techniques. Alpha decays of continuum levels populated using the ^1^2C(^1^6O, α) ^2^4Mg reaction were observed to the ground state and first two excited states of ^2^0Ne. Double (α-α) and, in some cases, triple (α-α-γ) angular correlation measurements were carried out for levels at E"x = 17.60, 17.86, 18.19, 18.56, 19.14, and 21.3 MeV. Branching ratios were determined for all of the above levels plus additional states at E"x = 19.37, 20.57 and 20.90 MeV. In most cases spin assignments could not be made from the angular correlations, either because of a strong continuum background or because the groups turned out to consist of more than one level. A search for a direct γ-decay branch of the E"x = 21.3 MeV level was carried out; a limit Γ"γ/Γ < 0.013 was obtained, in disagreement with a previously reported experiment. While the present work shows that the observed 21.3 MeV peak does not consist of a single state, the measured triple correlations provide some evidence for a J"π = 10^+ level at this energy. |

A study of the region of excitation energy between 17.5 and 22 MeV has been carried out using angular correlation techniques. Alpha decays of continuum levels populated using the ^1^2C(^1^6O, α) ^2^4Mg reaction were observed to the ground state and first two excited states of ^2^0Ne. Double (α-α) and, in some cases, triple (α-α-γ) angular correlation measurements were carried out for levels at E"x = 17.60, 17.86, 18.19, 18.56, 19.14, and 21.3 MeV. Branching ratios were determined for all of the above levels plus additional states at E"x = 19.37, 20.57 and 20.90 MeV. In most cases spin assignments could not be made from the angular correlations, either because of a strong continuum background or because the groups turned out to consist of more than one level. A search for a direct γ-decay branch of the E"x = 21.3 MeV level was carried out; a limit Γ"γ/Γ < 0.013 was obtained, in disagreement with a previously reported experiment. While the present work shows that the observed 21.3 MeV peak does not consist of a single state, the measured triple correlations provide some evidence for a J"π = 10^+ level at this energy. |
