Marian Danysz
Encyclopedia
Marian Danysz was a Polish
physicist
.
Son of Jan Kazimierz Danysz
. In 1952, he co-discovered with Jerzy Pniewski
a new kind of matter, an atom
ic nucleus, which alongside a proton
and neutron
contains a third particle: the lambda hyperon
.
Ten years later, they obtained a hypernucleus
in excited state, and the following year a hypernucleus with two lambda hyperons.

Physicist
A physicist is a scientist who studies or practices physics. Physicists study a wide range of physical phenomena in many branches of physics spanning all length scales: from sub-atomic particles of which all ordinary matter is made to the behavior of the material Universe as a whole...

Atom
The atom is a basic unit of matter that consists of a dense central nucleus surrounded by a cloud of negatively charged electrons. The atomic nucleus contains a mix of positively charged protons and electrically neutral neutrons...

Proton
The proton is a subatomic particle with the symbol or and a positive electric charge of 1 elementary charge. One or more protons are present in the nucleus of each atom, along with neutrons. The number of protons in each atom is its atomic number....
and neutron
Neutron
The neutron is a subatomic hadron particle which has the symbol or , no net electric charge and a mass slightly larger than that of a proton. With the exception of hydrogen, nuclei of atoms consist of protons and neutrons, which are therefore collectively referred to as nucleons. The number of...

Hypernucleus
A hypernucleus is a nucleus which contains at least one hyperon in addition to nucleons. The first was discovered by Marian Danysz and Jerzy Pniewski in 1952....
