Calculation of transition matrix elements of double-beta decay using Skyrme-QRPA

我们开发了一套程序来计算中微子双β衰变的跃迁矩阵元素，以确定中微子的质量。已经对质量为150的区域周围的基态和激发态进行了计算。最重要的成就是，现在可以几乎精确地计算得到的中间态的重叠。这一成就是由最先进的计算机实现的，并且具有使随机相位近似应用于中微子双β衰变比以前更精确的效果。

We developed a system of programs to calculate transition matrix elements of the neutrinoless double-beta decay for determining the neutrino mass. Calculations have been performed of the ground and excited states necessary around a mass-150 region. The most siginificant achievement is that the overlap of the intermediate states obtained can now be calculated almost exactly. This achievement was enabled by the most advanced computers and has an effect to make the application of the random-phase approximation to the neutrinoless double beta decay more acccurate than before.
