论文摘要
从$^{11} $中的低洼负值状态的光谱因素从$^{12} $ b（$ d $，$ d $，$^3 $ he）$^{11} $中提取为质子收集反应。 Earlier predictions of the $p$-wave proton removal strengths in the strong coupling limit of the Nilsson model underestimated the spectroscopic factors to the $3/2^-_1$ and $5/2^-_1$ states and suggested that deviations in the $1^+$ ground state of the odd-odd $^{12}$B due to Coriolis coupling should be further explored.在这项工作中，我们使用粒子转子模型考虑了这些效果，并在$^{11} $ b中获得了对级别方案的良好描述，其中Proton Nilsson级别的中等$ k $ - 混合[110] 1/2和[101] 3/2。这种混合存在于$^{12} $ b的$ 1^+$ bandhead中，是解释质子拾取数据的关键。
Spectroscopic factors to low-lying negative-parity states in $^{11}$Be extracted from the $^{12}$B($d$,$^3$He)$^{11}$Be proton-removal reaction are interpreted within the rotational model. Earlier predictions of the $p$-wave proton removal strengths in the strong coupling limit of the Nilsson model underestimated the spectroscopic factors to the $3/2^-_1$ and $5/2^-_1$ states and suggested that deviations in the $1^+$ ground state of the odd-odd $^{12}$B due to Coriolis coupling should be further explored. In this work we use the Particle Rotor Model to take into account these effects and obtain a good description of the level scheme in $^{11}$B, with a moderate $K$-mixing of the proton Nilsson levels [110]1/2 and [101]3/2. This mixing, present in the $1^+$ bandhead of $^{12}$B, is key to explaining the proton pickup data.
