Mostly not possible.........................

Explanation:

This is a very hard question and I think no one could solve this question because this is listed in the list of unsolved questions in physics.

Free neutrons are unstable with a half life of 10 minutes,11 seconds .It decays via beta decay# (beta^(-) "decay" )#

Beta Decay

Beta decay is a very complicated process and involves one of the fermions,upp quarks and down quarks

As you must know a neutron is made 2 down quarks and 1 upp quark

A free neutron is not stable. The upp quark in the neutron get converted into a down neutron and a W boson. This can be represented in an equation

#"udd" rarr "uud" + W boson#

Obtaining from this equation

#u rarr "W boson"#

This means the weight of W boson

Mass of upp quark = 2.15 mega electron volts

1 #"MeV" = 1.6xx10^(-19)J#

#therefore # #2.15MeV = 2.15 xx (1.6xx10^(-19)J)#

= #3.44e-19J#

#E = mc^2#

c is speed of light

We know the energy calculate the mass

#3.44e-19 = "299,792,458/s"^2x#

Calculate x

#1.1474605e-27kg#

Some others say 2.4572e-22 kg

#therefore# Mass of W Boson = #2.4572e-22 kg - "mass of down quark" #

The W boson later decays to form an antineutrino and a electron

#"W boson" rarr "antineutrino" + "electron"#

So you can say neutrons can't say stable.After 2 neutrons being bonded there are no trineutrons nor tetraneutron and Pentaneutron.
