Description

It is calculated, for the first time, the state-dependent pairing gap of a finite nucleus (120Sn) diagonalizing the bare nucleon-nucleon potential in a Hartree-Fock basis. The resulting gap accounts for about half of the experimental gap. Examples for light, halo nuclei are also reported. The more studied effects of the particle-vibration coupling in the particle-hole channel are discussed

Abstract (Russian)

Впервые вычисляется зазор спаривания конечного ядра 120Sn в зависимости от его состояния. Используется метод диагонализации нуклон-нуклонного потенциала в базисе Хартри-Фока. Полученный зазаор составляет около половины экспериментального. Описываются также примеры гало легких ядер. Обсуждаются эффекты связи частица-вибрация в канале частица-дырка
