摘要：
We have studied the competition between different decay modes such as alpha decay, beta decay, electron capture and proton decay for lanthanide nuclei. This study enable us to identify the dominant decay mode. By studying the different decay properties, we have predicted 79 new isotopes in the lanthanide region. Twenty-four new β+\documentclass[12pt]{minimal}
