On Monday, 23 September 2019, the 23rd International School on Nuclear Physics and Applications started in Varna, Bulgaria.

The School is organized by the Institute for Nuclear Research and Nuclear Energy of the Bulgarian Academy of Sciences with the support of the Joint Institute for Nuclear Research. The first School of the series took place in 1973, and has been biannually held since then.

The main goal of the School is to stimulate the activity of the nuclear physics community in the southeastern part of Europe, but it is a forum, where prominent physicists and young colleagues from all over the world come together and discuss the most interesting experimental and theoretical topics in the field.

This year, more than 80 scientists from different countries have come to Bulgaria to participate in the School.

The main topics of the Conference are the following:

• Nuclear excitations at various energies
• Nuclei at high angular moments and temperature
• Structure and reactions far from stability
• Symmetries and collective phenomena
• Methods for lifetime measurements
• Astrophysical aspects of nuclear structure
• Neutron nuclear physics
• Nuclear data
• Advanced methods in nuclear waste treatment
• Nuclear methods for applications

The programme of the meeting includes invited talks, oral and poster reports. It is expected that during the meeting there will be enough time for informal talks at which participants will have an opportunity to discuss future prospects of joining the efforts of different scientific centres for performing joint investigations.

The School proceedings will be published in Journal of Physics: Conference Series.

The School will be concluded on 28 September.
